UE described herein can comprise or represent by any equipment used for radio communication.The example that can be used in the subscriber equipment in some embodiment of described wireless and mobile network is following wireless device, such as mobile phone, mobile terminal, terminal, stand (such as, in IEEE 802.11 standard, UE can be station (STA)), smart phone, the portable computing device of such as laptop computer, portable equipment, flat computer, net book, computer, personal digital assistant, the machine to machine equipment of such as transducer or meter (such as, following wireless device, wherein there is not the terminal use be associated with this equipment), and other Wireless Telecom Equipments that are wireless and/or mobile network can be connected to.
Different business branch (segment) for the integrated possibility relevant with Wi-Fi can be divided into: the Wi-Fi access point that Wi-Fi access point vs the 3rd side that mobile operator presides over/controls presides over/controls.3rd side is considered other things any except mobile operator, and the 3rd side AP is not moved operator completely " trust " usually.3rd side can be, such as, and Wi-Fi operator or or even terminal use.The deployment of public/focus, enterprise and house is all there is in this Liang Ge branch.
There is integrated to mobile network of various types of Wi-Fi, in order to simply, herein by the mode being only example describe use System Architecture Evolution (SAE)/LTE node the 3rd generation partner program (3GPP) network symbol.But, to recognize, similar or similar network entity or node can be used in any other mobile network, such as, the mobile network of 2G/3G/4G and higher G, such as GSM, WCDMA, Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network network (UTRAN), enhancement mode-UTRAN, LTE and LTE-are senior.
Wi-Fi to mobile core network (also referred to as cellular core network) integrated emerging in large numbers become the access of a kind of honeycomb in each operator and Wi-Fi access between the further good way improving end-user experience.These solutions are formed primarily of following composition: integrated to mobile core network of the common certification between 3GPP and Wi-Fi and Wi-Fi user plane traffic.Common certification is based on the automatic certification based on SIM in these two kinds of access styles.Wi-Fi user plane integrated to mobile operator provide in order to for via 3GPP and connect via both Wi-Fi time terminal use to provide same services (as the head of a family control and based on order method of payment) chance.Different solutions is defined in standardized 3GPP technical specification 23.402, and can comprise and cover repeatedly solution (S2b, S2c) and integrated solution (S2a), they are current by exploitation further (S2a, S2b, S2c instruction is towards the 3GPP interfaces/reference points title of packet data network (PDN) gateway (PDN-GW)).
Fig. 1 a illustrates a kind of network architecture of simplification of the communication system 100 for comprising communication network 101 (also referred to as mobile or cellular network), and wherein communication network 101 (by circular dotted lines region representation) comprises RAN 102 and core network 103 part.Core Network elements 103 is by square dotted lines region representation, and RAN 102 is by short stroke of dotted lines region representation.Communication system 100 also comprises WLAN 104 and further IP network 118 (such as the Internet or any other network).Wireless network 104 is by dash line region representation.Communication network 101, IP network 118 and WLAN 104 link together via various communication path and are in communication each other.In this illustration, communication network 101 is illustrated as with WLAN 104 integrated.
In this illustration, communication network 101 is network based on LTE and RAN 102 comprises eNodeB 108, eNodeB 108 is connected to Core Network elements 103 respectively Mobility Management Entity (MME) 115 and gateway (SGW) 116 via S1-interface (such as S1-MME and S1-U).Core Network elements 103 also comprises home subscriber servers 121 (HSS) and Proxy-Call Session Control Function (P-CSCF, not shown) except other network node and element.ENodeB 108 serves or supports the network cell 106 that indicated by dashed double dotted line region.WLAN 104 is Wi-Fi access network (AN) in this illustration, and it is connected to the PDN-GW 117 of Core Network elements 103 and is connected to 3GPP authentication, authorization, accounting (AAA) server 119 via STa interface via S2a interface.WLAN 104 comprises WAP (wireless access point) (AP) 112, and it is Wi-Fi AP.Wireless aps 112 is connected to Radio Access Controller (AC) 113, and it is Wi-FiAC in this illustration.WLAN 104 directly or via PDN-GW 117 can be connected to further IP network (such as the Internet) via Core Network elements 103 by wireless AC 113.
Network cell 106 and WLAN 104 comprise UE 110, UE 110 and comprise for carrying out with eNodeB 108 radio access technologies (RAT) that communicates, and eNodeB 108 supports or serves UE 110.As shown, UE 110 is in the communication of the eNodeB108 of RAN 102, and can comprise the RAT be applicable to for carrying out communicating via wireless aps 112 and WLAN 104.When communication network 101 is integrated with WLAN 104 (such as, S2a link via between PDN-GW 117 and wireless AC 113), wireless AC 113 with for communicating authorizing UE 110 to access WLAN 104 and access via WLAN 104 the 3GPP aaa server 119 used in communication network 101.If communication network 101 is not integrated with WLAN (such as, not having S2a link), then wireless AC still can with for communicating at the 3GPP aaa server 119 of authorizing UE 110 to access to use in WLAN 104.
Although described above is a kind of deployment to select, those skilled in the art will recognize, exist and select for mobile network and wireless network are carried out integrated multiple deployment.Some examples can comprise: wireless AC 113 is connected to wideband network gateway (BNG) (not shown) so that wireless network 104 is connected to further IP network 118 and PDN GW 117; By wireless aps 112 and residential gateway (RG) juxtaposition, as in the above example, do not utilize BNG to dispose wireless aps 112 and wireless AC 113; Or even utilize RG and BNG but do not utilize wireless AC 113 to dispose wireless aps 112.In addition, will recognize to there are the multiple choices being used for terminating/connection S2a interface.Some further examples comprise, and S2a interface to be connected between wireless aps 112/RG and PDN GW 117, between wireless AC 113 and PDN GW 117 (as shown in the example of Fig. 1 a), between BNG and PDN GW117 or between exclusive credible WLAN (WLAN) IAD (TWAG) and PDN GW 117.
Fig. 1 b illustrates the WLAN possible when UE 110 initiates based on IEEE 802.11 standard or be connected to WLAN 104 and accesses message.UE 110 and wireless aps 112 carry out the service associating to obtain WLAN 104, and wherein association is following process, and UE adds WLAN 104 by this process.UE 110 initiates association process, and wireless aps 112 can be selected to grant or rejection access based on the content of association request.If UE 110 moves between the basic service region in the coverage of single expansion, then it must be assessed signal strength signal intensity and perhaps switch to another wireless aps (not shown) from wireless aps 112.Certification is the prerequisite of the necessity for association, because only there is certified user just can be authorized to use WLAN 104.
Fig. 1 c illustrates the possible WLAN be used to being connected to WLAN104 for UE 110 via wireless aps 112 and AC 113 during WLAN 104 certification UE 110 when Extensible Authentication Protocol (EAP) signaling and accesses message.UE 110 uses IMSI or certain other certificates to identify it oneself to WLAN 104.Note, IEEE 802.11 authentication response only open limited port goes on to allow EAP certification.IEEE 802.11 layer of 2 associated response only provides " unsettled association ", and is associated in completely and is just granted when being successfully completed of EAP certification.When UE 110 accesses WLAN 104, can use such as EAP-subscriber identity module (SIM)/EAP-certification and cryptographic key agreement (AKA)/EAP-AKA Prime (AKA ') agreement come certification it.In such cases, by access identifier of authenticating network completely (NAI) or UE 110 can be identified by quick re-authentication NAI.Certification NAI comprises International Mobile Subscriber mark (IMSI) of UE 110 completely, and re-authentication NAI is similar to the temporary mark of use in LTE access and is called as quick re-authentication mark or assumed name (pseudonym) fast.
As discussed above, different normal structures has started the demand of the Consumer's Experience recognized for the enhancing for Wi-Fi access, and it driven by 3GPP operator.The example of this point has the Wi-Fi Alliance that Hot-Spot 2.0 (HS2.0) formulates, and present official is called PassPoint.HS2.0 is mainly adapted to Wi-Fi network.HS2.0 is structured on IEEE 802.11u, and with the addition of requirement to authentication mechanism and automatic supply support.3GPP operator is attempting introducing additional flow control ability, to utilize HS2.0802.11u mechanism.HS2.0 uses access network vlan query protocol VLAN (ANQP) to find and the part of selection function as WLAN.This is that UE (and old-fashioned UE) provides a kind of mechanism and comes from the different information of wireless aps request, is namely determining whether be connected to wireless aps 112 with before the associating of wireless aps 112 to allow UE 110.
Fig. 1 d illustrates UE 110 during the initiation/connection to WLAN 104, uses generic advertisement service (GAS) agreement for delivering ANQP request.ANQP request be included in GAS message (GAS query frame), and allow UE 110 association before for configuration and reachability information to inquire about wireless aps 112.UE 110 launches ANQP inquiry in GAS message.Such as, in Fig. 1 d, UE 110 launch in GAS request message comprise ANQP request " ANQP (3GPP cellular network information) ", it is the request for the 3GPP cellular information from WLAN 104.Wireless aps 112 can use GAS response message (such as, GAS response frame) to respond.The list of the service provider that ANQP provides and ability can become expansion, and whether the information of fetching from GAS server (not shown) can be used by UE 110 and decide it and want to be connected to wireless aps 112.ANQP inquiry in GAS request can return with place title (Venue Name) information, network authentication type information, roams alliance's list, IP address class type availability information, the list of NAI field, 3GPP cellular network information, domain name list, hot spot operator friendly name, class of operation, focus WAN measure, focus concatenation ability, NAI belong to the information that field is associated.
But, the method being connected to wireless aps 112 for UE and old-fashioned UE above only the Wi-Fi of UE access/associate attempt time or just take action to refuse/accept access attempts during it, and normally after authentication.These actions may be refusals or accept access attempts.When admission reject, subject matter is the delay when refused UE 110 and minimize in UE 110 access attempts.Usually, preferably ,/connection procedure early stage is initiated at WLAN 104, i.e. during the initial creation of 802.11 layer of 2 association (such as, before EAP certification), the access attempts of refusal UE 110.But the persistent identifier (IMSI) of UE is generally disabled in this stage, because the Wi-Fi MAC Address of UE is used.This be applicable to certification completely and quick re-authentication (EAP-SIM/AKA/AKA ') both.Alternatively, in this process after a while (such as after EAP-SIM/AKA/AKA ' certification, when the IMSI of UE is known on the network side and is certified) to refuse access attempts be possible, but when access attempts such as during EAP-SIM/AKA/AKA ' certification or after, or or even when being rejected during dhcp process do not define UE behavior.When UE 110 lacks the access to communication network 101 during WLAN 104 access attempts, such as, when terminal use has closed or have disabled the data access via communication network 101 (such as 3GPP), or when UE 110 is outside communication network 101 covers, there is further problem.But, when other terminal use can alternatively be rejected for the preference of data, services or ability access communication network 110 owing to them, do not have for WLAN 104 method to determine user/UE preference or or even minimizing at UE 110 place ability (such as, lack data access), and depend on that load may refuse the access attempts of UE 110.
Therefore, there is the remarkable demand providing following mechanism, this mechanism is used for providing UE information to WLAN 104 efficiently, for using promptly determining whether that permission UE is linked in this WLAN.

Embodiment
In order to above overcoming for the problem being provided for solution that UE can carry out initiating/be connected with WLAN at present and identifying, this document describes method and apparatus or network entity, to consider the ability of UE, preference or state, UE is allowed to access WLAN for determining whether efficiently.The invention provides following advantage: use existing mechanism to consider for the change in the UE state of communication network, to determine which UE needs most access WLAN more exactly.As the current method for WLAN and communication network being carried out integrated (such as, in Wi-Fi to 3GPP network) described by about Fig. 1 a to 1d, the Wi-Fi/3GPP RAN supplied for WLAN/ network control is not had to access the good support selected.Have realized that, although increasing equipment can use WLAN, but be also importantly, when determining whether UE should access WLAN, WLAN determines or other network node/entities determine the UE that not necessarily may can receive equivalent data service from communication network.Current, for WLAN or network entity, there is no method determine, or for UE, there is no method to notify WLAN or network entity: UE for communication network state (such as, whether communication network can provide the WLAN data, services that can provide to UE, and/or UE whether preference access WLAN with alternative communication network), with based on can the knowledge that accesses of dissimilar network/service determine whether UE should move between communication network and WLAN.
Any data that term as described herein " the UE state for communication network ", " UE state information " or " the UE state for communication network " can comprise or be expressed as follows, the network information that this data representation is associated with UE and/or access the preference information that one or more network is associated with UE.The example that can be used in " the UE state for communication network " in some embodiment of described network comprises by only the mode of example: represent whether only WLAN accesses the data activated in UE, represent that the chlamydate RAN of tool does not access the data whether activated, represent that the RAN with limited service accesses the data whether activated, represent the data for the user preference (such as, for user or the UE preference of (multiple) WLAN access attempts) accessing or do not access communication network, RAN or core network accessibility information (such as, 3GPP accessibility information), the mark of UE or identifier, UE mobility, load on communication network, for the radio-link performance of the UE in communication network, radio access technologies (RAT) restriction of communication network or other networks, the subscription profile of the terminal use be associated with UE, and/or any other following UE state or information, it may be useful preference information for making the decision whether allowing UE to access one or more network (such as, (multiple) communication network or WLAN etc.) that these other UE state or information relate to what be associated with UE, connectivity information, and/or ability information.Also illustrate the further example of UE state or the UE state for communication network below.
Basic conception of the present invention is to provide a kind of network entity, device or method/process, with based on UE for communication network state (such as, cover, available service or 3GPP accessibility) instruction, determine whether to allow UE to be linked into WLAN.The instruction of UE state information is supplied to WLAN by UE, utilize this information, suitable network entity in WLAN or communication network and/or WLAN can determine whether to give priority that UE accesses WLAN (but such as, for can accessing 3GPP network not having the UE of 3GPP accessibility for a certain reason).This indication information is integrated into the RAN of communication network (such as at WLAN, 3GPP RAN) in situation in can be useful, thus can at WLAN place based on from UE information and also have and determine information to make decision from the access of the communication network be associated with UE (such as, 3GPP RAN side).
Such as, UE can access in message at one or more WLAN and indicate it for the state (such as, 3GPP accessibility) of communication network to WLAN, and this one or more WLAN accesses message to carry out being transmitted to WLAN when initiating/connect at UE and WLAN.As a kind of example, for having the UE of 3GPP ability, 3GPP accessibility information can be placed on WLAN and access in message by UE.This information can be placed in the request message in initiating/connect between trial period message sequence to the UE of WLAN.Such as, the request message from UE of the following request message from Fig. 1 b-1d and/or WLAN or IEEE 802.11 based on any future can be used:
The expansion of the new argument in probe request message or (multiple) existing parameter;
The expansion of the new argument in GAS initial request message or (multiple) existing parameter;
The expansion of the new argument in IEEE 802.11 authentication request message or (multiple) existing parameter;
The expansion of the new argument in association request message or (multiple) existing parameter;
In the response determined certification (pass through/do not pass through) by the expansion of the new argument in any upstream EAP-SIM/AKA/AKA ' authentication signal before returning or (multiple) existing parameter; And
In the response determined certification (pass through/do not pass through) by the new signal launched from UE to WLAN before returning or request message.
3GPP accessibility information can comprise the data representing the following:
1. " only WLAN packet switching access activates in UE ", if its instruction WLAN access attempts should be allowed to, most possibly possible words;
2. " WLAN and 3GPP both activates but the state in 3GPP is ' without covering ' or ' limited service situation ' ", if its instruction WLAN access attempts should be allowed to, most possibly possible words; And
3. " WLAN access attempts is triggered by the preference of terminal use ", its instruction WLAN can determine whether the access of terminal use institute preference should be given priority.
Once be launched from UE and 3GPP accessibility information detected in therefore received in a wlan (multiple) WLAN access message, this information just can be used by WLAN, determine whether the access attempts be associated should be allowed to so that WLAN ought not be there is to during integrated (what such as, do not have Wi-Fi in disposed RAN solution is integrated) in communication network.Additionally, or alternatively, when exist WLAN in communication network integrated (such as, integrated in the RAN solution of such as disposing in fig 1 a of Wi-Fi) form time, this information can be transmitted to the different assemblies of integrated solution (such as by WLAN, be transmitted to the assembly in communication network, such as RAN or Core Network elements), wherein can make the decision whether allowing UE to be linked into WLAN in these assemblies of communication network.Then the decision made is forwarded to WLAN, and WLAN can include this decision in consideration, or processes this decision, or this is determined when determining whether that permission UE is linked into WLAN to combine with UE state information.
Fig. 2 a is a signaling process figure, which illustrates the process for being used by UE210 and network entity 215 in a communication system 200.Communication system 200 comprises communication network 201 and WLAN 204 (such as, IEEE 802.11WLAN).In this illustration, communication network 201 is knockdown UMTS and LTE network.Communication network 201 comprises RAN 202 and (multiple) Core Network elements 203.RAN 202 includes but not limited to: the one or more base stations 208 serving or support UE 210, in this illustration, base station 208 can be e/nodeB, and it is the eNodeB (eNB) for LTE network or the NodeB (NB) for UMTS network.RAN 202 also comprises the radio network controller (RNC) 209 for UMTS network.For LTE network, core 203 can based on System Architecture Evolution (SAE) core network architecture for 3GPP LTE wireless communication standard.WLAN 204 includes but not limited to: wireless aps 212 (such as, Wi-Fi AP), wireless AC 213 (such as, Wi-Fi AC) and network entity 215.Network entity 215 can be the independent community in WLAN, or it can be a part of wireless aps 212 or wireless AC 213.In fig. 2 a, WLAN 204 is not integrated with communication network 201.
In order to simply, the identical or similar reference number used in Fig. 2 a is reused in Fig. 2 b, 2c and 2d to identify identical or similar UE, network, network node, element or entity etc.Fig. 2 b is the indicative icon of another example of the communication system 200 comprised according to network entity 215 of the present invention, and communication system 200 has not integrated with some RAN 202a, 202b, 202c of some communication networks WLAN 204a and 204b.
Fig. 2 c is another signal flow graph, which illustrates another instantiation procedure for being used by UE 210 and network entity 215 in a communication system 200 when WLAN 204 is integrated with communication network 201.Fig. 2 d is the indicative icon of another example of the communication system 200 comprised according to network entity 215 of the present invention, and some RAN 202a, 202b, 202c of WLAN 204a and 204b and some communication networks are integrated.Fig. 2 e is the further diagram of the example communication system 200 comprised according to multiple network entity 215a-215c of the present invention and other network entity 216a-216c.
Although these examples describe some deployment and select, but those skilled in the art will recognize, there is the various ways and layout that are used for the network element of communication system or node (such as, base station 208 & 208a-208c, RAN 202a-202c, wireless aps 212 & 212a-212c and wireless AC213 & 213a-213c) to be connected with network entity 215,215a-215c.In essence, network entity 215 & 215a-215c can be connected to or be arranged in communication system 200, make it be in WLAN 204 (such as, via wireless AC 213 &/or 213a-213c or AP 212 &/or 212a-212c) and communication network is (such as, via RAN202,202a-202c, or Core Network elements 203) communication in.
With reference to figure 2a, in this illustration, RAN 202 is 3GPP RAN, such as UMTS/LTE, and wherein UE 210 is served in base station 208.In step 219, UE 210 be in the communication of communication network 201 in and register to RAN 202 (such as, eNodeB 208 or RNC 209) and/or (multiple) Core Network elements 203 (such as, SAE).UE 210 can also be communicated by communication network 201 via base station 208.On certain time point, in a step 220, UE 210 can determine to be connected to WLAN 204 and via wireless aps 212 to access WLAN 204.This may owing to the UE state in communication network 201.Such as, UE state can the preference of indicating user be connected to WLAN 204, and/or UE 210 may have limited 3GPP accessibility or the limited covering/service for communication network 201, and/or UE 210 may move to base station 208 or 3GPP network covering outside and so any data, services from communication network 201 can not be accessed.Alternatively, the UE state in communication network 201 can be actually the complete 3GPP accessibility (such as, covering completely) had communication network 201.In any situation, UE 210 determines for communication network 201 (such as, for (multiple) RAN part 202, such as the eNodeB 208 of LTE network and/or the RNC 209 for UMTS network; Or Core Network elements 203, such as the SAE of LTE network) UE state.
In step 221, UE 210 initiates/is connected the access attempts with WLAN via wireless aps 212 with wireless AC 213.In the process done like this, UE 210, by accessing the instruction of inserting the UE state for communication network in message to WLAN, is sent in the UE state in communication network.As described earlier, WLAN accesses message and can comprise the message, any one in request or signal that are used when initiating/being connected to WLAN 204 by UE 210.Such as, WLAN accesses any message that message can be group from the following, request or signal: probe request message; GAS initial request message; Authentication request message; Association request message; Authentication signal (such as, based on the signal of EAP-SIM/AKA/AKA ' authentication protocol) before the certification be associated with the UE 210 of access WLAN 204 determines; The complete authentication signal in upstream before the certification be associated with the UE 210 of access WLAN 204 determines; Upstream re-authentication signal before the certification be associated with the UE 210 of access WLAN 204 determines; Before determining with the certification that is associated of UE 210 of access WLAN 204 from UE 210 to WLAN 204 access signal; Or as any other the request of launching from UE 210 of a part for the initiation/connection procedure to WLAN 204, message or signal.
The instruction of UE state can comprise a part for the data of the group from the following: represent whether only WLAN accesses the data activated in UE; Represent that the chlamydate RAN of tool does not access the data whether activated; Represent that the RAN with limited service accesses the data whether activated; And/or expression is for the data of the user preference of WLAN access attempts.When RAN 202 is 3GPP RAN, then the instruction of UE state can comprise 3GPP accessibility information.The instruction of UE state can be included as the parameter in WLAN access message, or as WLAN being accessed to the expansion of the existing parameter in message.
In step 222, network entity 215 receives WLAN from UE 210 and accesses message.Network entity 215 can be the network element in WLAN 204, or it can be a part of wireless AC 213.Because WLAN access message comprises the instruction of the UE state for communication network 201.Network entity 215 uses the instruction of UE state to determine whether and allows UE 210 to be linked into WLAN 204.Network entity 215 can comprise the function of the instruction of the UE state detected in WLAN access message.
In step 223, whether network entity 215 is made and is allowed UE 210 to be linked into the relevant decision of WLAN 204.Such as, the instruction of UE state can comprise the information be associated with the UE state of the RAN 202 for communication network 201, (such as, RAN accessibility or 3GPP accessibility information), its can comprise expression whether only WLAN access in UE 210 activate data, wherein in step 223, network entity is made decision (determination) allows UE 210 to be linked into WLAN.The instruction of UE state can comprise and represent that the chlamydate RAN of tool does not access the data whether activated, wherein step 223 make decision (determination) allow UE 210 be linked into WLAN.
Alternatively or additionally, the instruction of UE state may further include and represents that the RAN with limited service access the data whether activated, and then step 223 (determination) permission UE 210 that makes decision is linked into WLAN 204.The instruction of UE state may further include the data represented for the user preference of WLAN access attempts, and then step 223 (can attempt the requirement of access WLAN 204 based on user preference owing to other UE (not shown), this user preference may not be guaranteed) when determining whether to be given priority to the WLAN of this UE access, include this information in consideration.Cover completely or the data of complete 3GPP accessibility to communication network 201 if the instruction of UE state comprises expression, then network entity 215 can depend on the load of WLAN 204 and/or the requirement of other UE (not shown), allows UE 210 to access WLAN 204.Such as, other UE may have for access WLAN 204 a higher priority (such as, these UE may have one of admissible condition above, such as, only WLAN access activates, or has the RAN access of limited service, or the not chlamydate RAN access of tool).Alternatively, WLAN can have the maximum restriction of the number for the UE being connected to it, if reach this restriction, new UE is not then had to be allowed to, or may can be rejected by the UE of telecommunication network services better, or the UE that (during this time) only has a WLAN ability can be allowed to relative to the UE with complete 3GPP accessibility.
In step 224, once with whether allow UE 210 to access the relevant decision of WLAN 204 to be made, WLAN 204 just can send to UE 210 and accept or the response of refusal UE access attempts.The time that this response is sent out can depend on that UE 210 and WLAN204 has completed the where in initiation/connection procedure.If determine it is refusal UE access attempts, then this can be transmitted to UE 210 immediately, even before the step of the certification/association in initiation/connection procedure.But if WLAN determines it is allow UE 210, then, after experience UE 210 and WLAN performs the remainder (if necessary) of initiation/connection procedure, WLAN 204 can send the response that accept UE access attempts to UE 210.In any situation, based on this decision, if WLAN 204 accepts UE access attempts, then in step 224, UE 210 accesses WLAN 204.Otherwise UE 210 can attempt another WLAN 204 and access, or access the data, services of equivalence via communication network 201.
Fig. 2 b is the indicative icon of another example according to network entity 215 of the present invention in the communication system 200 comprising some communication networks (such as, some RAN 202a-202c) and WLAN 204a-204b.In this illustration, WLAN 204a-204b is not integrated with communication network.Communication system 200 comprises the first and second UE 210a and 210b be in the communicating of at least one in some RAN 202a, 202b, 202c and/or some wireless network 204a with 204b.In this illustration, communication system 200 comprises: the GSM RAN 202a comprising base station 208a and base station controller (BSC) 209a, the WCDMA RAN 202b comprising nodeB 208b and radio network controller (RNC) 209b and comprise the 3GPP RAN 202c of enodeB 208c.WLAN 204a-204b is in the communication of network entity 215.Wireless network 204a comprises the wireless AC 213a of wireless aps 212a based on Wi-Fi or IEEE 802.11 standard and correspondence.Wireless network 204b comprises wireless AC 213b and 213c of the first wireless aps 212b and the second wireless aps 212c and correspondence.In order to simply, core network element RAN 202a-202c being connected to further IP network (such as, IP network 218) is not shown.
Network entity 215 can comprise as some in the function with reference to the process described by figure 2a and/or Fig. 2 d, 3a-5b or network entity or all functions.Because WLAN204a-204b is not integrated with communication network/RAN 202a-202c, so this means, network entity 215 depends on and accesses the instruction from the UE state for communication network/RAN 202a-202c of UE transmitting in message when initiating/being connected to WLAN 204a-204b at one or more WLAN.Each UE in UE 210a with 210b can be in the communicating of the RAN of in RAN 202a-202c, and can determine the UE state for corresponding communication network.Then UE 210a or 210b by initiating the access attempts with corresponding WLAN 204a-204b, and can access WLAN 204a or 204b via wireless aps 212a-212c.UE 210a and 210b can be configured to the instruction of UE state to be included in (described by with reference to figure 2a and/or 2e-5b) WLAN and access within message or signal, thus this WLAN message is transmitted to network entity 215 by WLAN 204a-204b, for detecting the instruction of UE state and determining whether that based on this instruction allowing UE to be linked in WLAN 204a-204b (described by with reference to figure 2a, 2d-5b) uses.
Fig. 2 c is another signal flow graph, which illustrates in a communication system 200 by another instantiation procedure used with reference to the UE 210 described by figure 2a and network entity 215.In this illustration, communication system 200 be arranged and make to exist WLAN in communication network 201 integrated (such as, integrated via in the RNC 209 for UMTS network or the eNodeB 208 to RAN 202 for LTE network of WLAN, or WLAN is via integrated in Core Network elements 203 of the SAE for LTE network).WLAN is illustrated to integrated (such as, via the S2a interface between wireless AC 113 and Core Network elements 103) in communication network in Fig. 1 a.In a communication system 200, this signal of communication/arrow illustrated in step 233a and 233b illustrates, they indicate exists following communication path, wireless AC 213 and/or network entity 215 are connected to RAN 202 via the RNC 209 for UMTS network or the eNodeB 208 for LTE network by these communication paths, and/or are connected to Core Network elements 203 via the SAE for LTE network.The step 219-221 performed by UE 210 be identical or similar with reference to the step 219-221 described by figure 2a, and the step 222 performed by network entity 215 be identical or similar with reference to the step 222 described by figure 2a.
If WLAN 204 via Core Network elements 203 (such as, SAE for LTE network) integrated with communication network 201, then in step 233a, network entity 215 sends inquiry, for determining based on received UE state whether WLAN should allow UE to be linked into WLAN 204 towards Core Network elements 203.If WLAN 204 uses the RNC 209 being used for UMTS network integrated with communication network 201 via RAN 202, then in step 233a, network entity 215 sends for determining or the inquiry of information with device-dependent towards RNC 209, this decision or be used for determining based on received UE state whether WLAN should allow UE to be linked in WLAN 204 and use with the information of device-dependent.If WLAN 204 uses the eNodeB 208 being used for LTE network integrated with communication network 201 via RAN 202, then in step 233b, network entity 215 sends for determining or the inquiry of information with device-dependent to eNodeB 208, this decision or be used for determining based on received UE state whether WLAN 204 should allow UE to be linked in WLAN 204 and use with the information of device-dependent.This inquiry can be forwarded to the other network entity (not shown) in communication network 201 (not shown), for the information depended in this inquiry (such as, for the UE state of communication network 201 instruction and also have the mark of UE 210) make decision, and to respond with the decision whether WLAN 204 should allow UE 210 to access.
Such as, communication network 201 can comprise other network entity (not shown) or wherein (such as, in RAN 202 or (multiple) Core Network elements 203) node, it can be configured to receive this inquiry or the request for the network information with device-dependent from WLAN 204 or network entity 215.Except for except the UE state of communication network 201, this inquiry at least can also comprise the identifier of UE 210.Then this other network entity is configured to, use UE 210 identifier and for the UE state of RAN 202 or eNodeB 208 and/or Core Network elements 203 or the network information relevant with UE, obtain and determine or the network information that is further and device-dependent, for determining whether UE 210 can access use in WLAN 204.Then this other network entity is configured to, and sends the response comprising the obtained decision information of device-dependent (or with) to network entity 215 or WLAN 204.By the other network entity in communication network 201 in order to obtain this decision or further and the network information of device-dependent and the step implemented, beyond the scope of method described herein; But, PCT/SE2012/051007 describes illustrative methods and the device of the function by being suitable for providing following other network entity, and this other network entity can to determine or further and the information of device-dependent based on the identifier of UE 210 and/or generate for the UE state of communication network 201.
